Precision Part for High-Flow Stream Pumps
Keep your large waterfall running strong with the genuine OEM replacement impeller for the TidalWave3 TT5000 waterfall and stream pump. This exact-fit impeller restores the TT5000 to its rated 5,150 GPH (19,493 LPH) output, maintaining the dramatic water volume that large-scale koi ponds and formal waterways demand.
Built for the TT5000's 2" Plumbing
The TT5000 operates with 2-inch inlet and outlet ports to handle its high flow capacity. The impeller is sized accordingly — a larger, more robust blade assembly than the smaller TT models. Using a genuine replacement part maintains the hydraulic match between impeller and housing that the factory engineered. Undersized or incorrect impellers cause cavitation and reduce the motor's service life.

Ideal for large Canadian koi ponds and formal stream installations requiring sustained high-volume flow.
